• High isolation voltage (typically 5000 Vrms)
• Current transfer ratio (CTR) of 50% to 600%
• Low saturation voltage
• Compact DIP-4 package
• Operating temperature range: -55°C to +110°C

Benefits

• Provides excellent electrical isolation, protecting sensitive circuits from high voltages and transients.
• Enables efficient signal transfer with a wide range of CTR values.
• Reduces power consumption and improves circuit efficiency.
• Easy to integrate into circuit boards.
• Offers reliable performance in harsh environments.

Additional Details

The TLP627F(D4,F comes in a 4-pin DIP package. The forward voltage of the input diode is typically 1.2V, and the collector-emitter voltage of the output transistor is 80V. The suffix (D4,F) indicates specific binning for CTR. It is crucial to consult the Toshiba datasheet for detailed specifications including minimum and maximum CTR values at different forward currents. The photocoupler is commonly used in applications requiring safety isolation. Proper external components (e.g., resistors) are necessary for setting the operating current of the LED and the load resistance of the transistor.
